motion vocbulary

4. acceleration If the object is slowing down then its acceleration vector is directed in the opposite direction as its motion
7. an amount of space between two things or people.
8. forces two forces acting on an object are equal in size but act in opposite directions
10. speed When the speed of an object remains the same - it does not increase or decrease
12. a course along which someone or something moves.
14. stationary is not moving
16. the indefinite continued progress of existence and events in the past, present, and future regarded as a whole.
18. an influence tending to change the motion of a body or produce motion or stress in a stationary body. The magnitude of such an influence is often calculated by multiplying the mass of the body by its acceleration.
19. the rate at which someone or something is able to move or operate.
21. a place where someone or something is located or has been put.

1. the action or process of moving or being moved.
2. acceleration the acceleration of an object in free fall within a vacuum
3. not impeded by or creating friction; smooth.
5. the rate of change of the velocity of an object with respect to time. Accelerations are vector quantities
6. The speed of something in a given direction.
9. forces When two forces acting on an object are not equal in sizeInertia: a property of matter that continues in its existing state of rest or uniform motion in a straight line, unless that state is changed by an external force.
11. the resistance that one surface or object encounters when moving over another.
12. the moving of something from its place or position.
13. the universal force of attraction acting between all matter.
15. Laws of Motion (3): when two bodies interact, they apply forces to one another that are equal in magnitude and opposite in direction.
17. a coherent, typically large body of matter with no definite shape.
20. force the force of attraction between all masses in the universe
